Promote AC_LANG_CASE.

* acgeneral.m4 (AC_TRY_COMPILER, AC_TRY_LINK_FUNC, AC_CHECK_LIB,
AC_TRY_COMPILE, AC_TRY_LINK, AC_TRY_RUN_NATIVE, AC_CHECK_FUNC):
Use AC_LANG_CASE instead of ifelse (AC_LANG, ...).
(AC_TRY_LINK_FUNC): Quote the body the the AC_DEFUN (whoa, how
could this survive so long?!?).

 I don't understand why we have this weird system of AC_SAVE and
